INTRODUCTION During mid-March, 2006, Big Red Diamond Corporation drilled 7 power auger drill holes and 3 hand auger holes to explore the Gervais property for a variety of mineral potentials. As kimberlite was recently intersected in drilling by Tom Exploration on a property directly to the to the east-south-east, diamond potential is possible. Recent diamond drill work on the Lakeshore Gold Property, 3 miles south and still in Bristol Twp. is defIning a signifIcant gold resource. Several gold showings on the western end of the Gervais property, near the township comer may indicate the possibility for significant structurally controlled gold mineralization, and most importantly, a base metal resource in Godfrey Twp. (Genex deposit) and the geological predisposition of the felsic rock underlaying the property to base metal deposition offer some degree of base metal potential. 13 till samples were subjected to heavy mineral concentration at True North Minerals Inc. HMC laboratory in Timmins, On. Concentrates were size fractioned and visually and microscopically examined for .. minerals of interest. Several possible kimberlite diamond indicator minerals were picked and sent to C.F.Minerals Resaearch for examination and possible microprobe work. The <20,>40 size fraction was examined microscopically for minerals associated with base metal or gold deposits. It is apparent that the sampled material is clay rich till. Several grains and populations of grains of interest were observed, and more work on the property is recommended.

PROPERTY DESCRIPTION Work was confmed to 5 mineral claims (3016548, 3016549, 3016550, 3012033, 3012034) in Bristol Twp. and Godfrey (Lots 5, 6, 7, and 8, Concession I) Twps., Porcupine Mining Division. See Figure 1.

ACCESS Access is readily available via the MontcalmlMalette all-season road which runs east­west though the property along the Godfrey-Bristol Twp. line. The road departs Highway 101 west from Timmins, 900 meters west of the Tembec-Malette mill. Several north south tertiary access roads allow further access to much of the property. A maintained Snowmobile trail cuts across the claims in question. The trail was minimally disturbed during the job. (r;::{~2. ')

WORK PROGRAM The fieldwork consisted of light weight power auger drilling. The drill itself is a "Pioneer" hydraulic drill, manufactured by Multi-Power Manufacturing of Kelowna B.C. A 25 HP .hydraulic motor turns 4112 inch continuous auger rods to a maximum depth of over 100 feet.. The rig is mounted on a customized eight wheel Argo off-road amphibious vehicle. .A driller and a helper run the drill, I or 2 labourers clear trails for the Argo when necessary and haul equipment around. A sizable Snowmobile is used to haul the 5 foot, 50 pound, auger rods 2 to 3 samples are taken per hole, usually based on variation of material type (i.e. colour change). The deepest material is always sampled. Sample locations are given on Table 1, shown on Figure 3 and logs for the sample holes are found in Appendix I. Seven Auger holes were drilled with ten samples taken. 3 hand auger samples were drilled for three more samples. Samples were subjected to Heavy Mineral Concentration and KIM grain picking as described in Appendix II. Sieving results are given in Table 2. Several possible KIM grains were picked (Table 3) and sent to C.F.Mineral Resarch for further analysis including SEM and microprobe work. Results are shown on Table 4 and the C.F.Mineral Research codes and procedures are found in Appendix III. The <20>40 picked heavy fraction was visually analyzed for sulfide and exotic minerals, The unpicked portion and magnetic portion of the same fraction was examined for several samples and the <12 coarse fraction for all samples was examined .. Notes are included as such (Appendix IV)

RESULTS Clay tills were encountered and sampled in every hole. As wet clay content was generally high to the end of the holes it cannot be determined whether the till is basal. Visual examination of the <12 mesh fraction for all of the samples indicates that the material is homogenously heterogeneous across the property with local input well represented in some samples. Drillers report a general change to a darker, more rusty brown clay within 1 meter of bottom of hole. Several of the samples have variably oxidized fragments of a variety of lithologies. Coarse Fraction is usually composed of 50 % grey, variable intermediate to volcanic rocks. 15 to 20% is composed of granitic to gneissic rocks. The balance is filled a variety of rocks including metasediments, limestones, jasper. The material is unsorted and well mixed, variably rounded with a tendency to anguilar and spans all sizes from pebble to cobble, With a general uniformity to the host till in the area, it can be fairly safely assumed that anomalies within the sample group are anomalous even though regional background values for any minerals have yet to be calculated and sample size (picked grains) is very small .. Several grains were sent for SEM and microprobe analysis. Of 13 grains submitted, 3 were of no consequence and 10 proved to be of most probable kimberlitic origin (KIM). Unfortunatly, none of the grains proved to be diamond indicator minerals.(DIM's). Visual analysis of sulfides turned up an apparent sphalerite anomaly in holes 6, and 9. Several highly angular grains of brown refractory sphalerite were found in hand auger hole OVB-6. Hole OVB-9 showed 20% brown sphalerite of picks from concentrate. A significant amount of pyrite in Sample 10 (90% of picks from concentrate are bright fine

RECOMMENDATIONS I

Base metal mineralization found in picked heavy mineral concentrates from the program should he followed up. Several previously detected airborne EM (Megatem) conductors in the immediate vicinity of hole OVB-9 should be ground delineated with an HLEM survey for possible diamond drilling. Further laboratory work should include identification of the numerous clear to opaque white heavy grains and silvery minerals found in the HMC and pertinent samples, if volume proves sufficient, should be subjected to Neutron Activation Analysis (NAA) to verify conclusions from visual examination. Remaining picks should be averaged against remains for each sample.

Material Handling Prior to Analysis - Methods and Procedures

1. Recording Sample Information

The sample is weighed, information is taken from a field book, sample log and hand written weight logs and entered into appropriate computer spreadsheet(s). Hand written location coordinates are normally cross checked against stored GPS waypoints if available. Often, GPS waypoints are downloaded into a computer and archived at this time as further backup. An effort for completeness is made to properly document the following information prior to the start of sample processing as it is critical sample information: ~

• Sample location - in NAD83, UTM coordinates including zone number. • Sample logs - type, depth (if auger), material description, observations. • Sample weight - full sample weight as it arrived from the field.

Weighing Field Sample Cleaning sieves Typical sieve arrangement 2. Sieving, Sorting, Pre-wash

The sieves are thoroughly cleaned and inspected to eliminate any possibility of contamination from previous samples. The sample is washed through a stack of sieves. This process provides a preliminary wash for the mineral grains and sorts them by size. Selection of appropriate sieve mesh sizes can vary according to the type of material be4tg sorted. Typical sieve sizes used are (Tyler mesh) #12, #20, #40 and #70.

Stated as metric equivalents: #12 = 1.7mm

#20 = 0.85mm #40 =0.43mm #70 = 0.21mm

Sieve mesh sizes used for any particular sample can be found in the attached appencies that provide sample weights and mineral grain observations. Normally a lower size limit is determined and accepted beforehand. Sample material smaller than the lowest mesh size is normally washed away. In. some cases all of the fine material is kept for possible microscope study, particularly in the case of an expensive sample.

3. Washing

Each resulting size fraction is washed thoroughly with clean water and dish soap as it is removed from the sieves. Any organic material remaining with each fraction is floated off and washed away through repeated washing and rinsing. Washing is complete when the mineral grains are free of any organics, soap and fine silt.

4. Drying

The resulting, washed fractions are then dried. An oven can be used to speed drying time. Once dry each of the size fractions is bagged in a plastic zip-Ioc bag and weighed. The resulting weight is recorded in both hand written log form and on computer spreadsheet. Clear labels must accompany each fraction through aU remaining procedures.

Drying sample fractions Fractions bagged and Jabelled Fractions weighed 5. Heavy Liquid Separation

The resulting size fractions are looked at to determine which fraction(s) are suitable for heavy liquid separation. Larger size fractions may not contain enough mineral grains to make heavy liquid separation worthwhile. Program budget may limit the number of heavy liquid separations per sample or sample program. Smaller size fractions can provide the greatest number of heavy grains for observation in the resulting heavy mineral concentrate. However, fine grains can be more difficult to handle during microscope work. Each sample will have one ore more size fractions that are better suited for the process than the others.

The selected size fraction is run through a heavy liquid process where all grains having a density greater then 2.85 glml (sinks) are separated from the lighter fraction material (floats). All kimberlite indicator minerals will sink as will many other minerals of economic interest, such as gold.

Both the sinks and floats are rinsed thoroughly in distilled water. The distilled water is saved for recycling as most of the expensive heavy liquid can be recaptured later. Both portions are then dried. An oven can be used to speed drying time. The floats are normally put in storage as the grains may warrant further study should the heavy mineral portion yield positive results. Abrasion due to grain transport for example, can help to determine transport distance. The sinks, or heavy mineral concentrate moves on to the next stage.

Typical yield of Heavy Minerals Floats (less than 2.85 glml) stored 6. Observation and Picking

The microscope observation table and surrounding area must be thoroughly cleaned to ensure there are no grains around from past samples. A clean paper table cover is placed under the microscope to cover the surrounding table top. AU grain handling is done on the table cover.

Small portions of heavy mineral concentrate are placed in plastic dishes in preparation for microscope observation. A small hand magnet is used to pun out and separate any magnetic grains from each dish. The magnetic grains are carefully placed into a separate dish for observation. This portion will be stored separately in a numbered plastic viaL

The non-magnetic portion of the heavy mineral concentrate is observed using binocular microscope and a good light source. When visually identified, kimberlite indicator minerals or any mineral grains of interest are manually picked using tweezers and placed in a numbered plastic vial. A computer log is maintained during observation where notes are linked to sample number, fraction, vial number and other basic information. When observation of each dish is complete, any remaining, unpicked grains are placed into a separate, numbered plastic vial using a small funnel. Observation notes are backed up regularly onto CD and archived. All vials are weighed on a fme scale and documented by hand written log and computer spreadsheet before storage.

Important grains or vials of picked grains that are selected for further analysis, such as SEM and microprobe are photographed through the microscope using a digital camera. Total number of grains to be sent for analysis is verified by counting them on the digital image using suitable graphics software. Normally all grains sent for SEM or microprobe analysis are returned, mounted on a slide or plug. The digital photograph, observation notes and grain count can be used at that time for basic verification and identification of analyzed grains. Copies of the digital photographs can be shipped to the analytical lab along with the selected vials of grains. This helps the receiver to confirm all grains were received and discrepancies can be noted by both parties.

SAMPLE PREPARATION, ANALYSES AND SECURITY

At the C.F. Mineral Research laboratory, the samples underwent wet sieving, dry sieving, heavy liquids separation and electromagnetic separation to concentrate heavy minerals. Heavy mineral fractions of -20+80HIL and -20+80HPYCRD were examined under binocular microscopes and any potential diamond indicators were carefully extracted.

To maintain quality control, each heavy mineral sample was examined by at least two laboratory personnel: a first-pass picking by a laboratory technician and a second-pass picking/checking by a senior laboratory technician. Work by the senior technicians were also checked routinely. Any missed Indicator grains were recorded, added to the picking results and included for subsequent analyses.

The picked grains were encapsulated in epoxy mounts and scanned qualitatively using a Scanning Electron Microscope (SEM). Based on the scans, potential diamond indicators were selected for quantitative analyses utHising a CAMECA SX-50 electron microprobe.

Before starting a microprobe run, a number of mineral standards were analysed to verify the consistency and reliability of the instrument. Results of the standards were compared to known values obtained previously at C.F. Mineral Research and at various laboratories world-wide. Any unsatisfactory results in the standards were corrected immediately by calibration or verification of spectrometer positions. and the standards were rerun.

Once the standard results were satisfactory, an analytical run would be set up consisting of standards and the relevant samples. Standards were analysed at the begInning and the end of each run, and at intervals of every 100 to 120 analyses. When an analysiS run was completed, the results were classified by a proprietary computer program to identify and rank diamond indicators.

As the exploration program is at an early stage, security of the samples is not considered a problem.
